Which is an equation of the form and implies that the states are either orthogonal or the same state. Making use of the unitary operator's properties and the orthonormality of the states, we can say that To clone or copy an unknown quantum state, the required process is We recently saw the no-cloning theorem in my quantum optics class, but I feel like I am missing something about it's significance. Therefore, there must be some other obstacle that the book omitted. Bob needs to measure gibberish without Alice's classical bits.

This theorem was proved by William Wooters and Wojciech Zurek in 1982. In algebraic terms, a 2 + b 2 c 2 where c is the hypotenuse while a and b are the sides of the triangle. A result stating that it is not possible to copy quantum information perfectly. Pythagoras' Theorem then claims that the sum of (the areas of) two small squares equals (the area of) the large one. The qubits could all collapse differently, but what if the state is on an axis? Or, for simplicity, what if the unknown state is |0> or |1>? The defense of the no-cloning theorem states that the problem arises if Bob can make measurements that are all zeroes or all ones. Let's build up squares on the sides of a right triangle. The no-cloning defense suggests that as long as Alice measures her qubits, Bob could perform a bunch of measurements and figure out the unknown state. 5: Prime Number Theorem: Jacques Hadamard and Charles-Jean de la Vallee Poussin (separately) 1896: 6: Godel’s Incompleteness Theorem: Kurt Godel: 1931: 7. However, what if Alice prepared multiple qubits with the same state? Instead of cloning, she uses identical preparation, and then teleports all those qubits to Bob. Fundamental Theorem of Algebra: Karl Frederich Gauss: 1799: 3: The Denumerability of the Rational Numbers: Georg Cantor: 1867: 4: Pythagorean Theorem: Pythagoras and his school: 500 B.C. But, cloning is impossible so the authors left it at that. As long as she at least measured her qubits, and as long as Bob could make a sufficient number of z and x measurements, Bob could basically use tomography to determine the unknown state. It states that if Bob could clone his qubit many times, that would permit him to determine the teleported state of Alice's qubit. You can easily improve your search by specifying the number of letters in the answer. I just read in a book - not some blog article or YouTube comment - a questionable explanation of the no-cloning theorem.
